How it is calculated
From Celsius to Fahrenheit, multiply by 9/5 and add 32. Kelvin = Celsius + 273,15. The reverse formulas on the screen are already applied to all three scales.
°F = °C × 9/5 + 32, K = °C + 273,15, °Ré = °C × 4/5

Example
0 °C = 32 °F = 273,15 K. 100 °C = 212 °F.
Questions
Why not just multiply?
The scales have different zeros. A multiplier with no shift converts a temperature difference, but not a reading on a thermometer.
Is absolute zero in the list?
Not as a point, but 0 K corresponds to −273,15 °C.
Is Réaumur supported?
No, only the three scales that come up at home and at school.
